ClassNotFoundException javax.mail.internet.AddressException when running hibernate3:hbm2ddl - log4j

Question

So I'm having trouble with log4j and hbm2ddl.
When I put an SMTPAppender in my log4j.xml I get this ClaasNotFoundException.
Any Hints on how to solve this?
These are my config files and the stacktrace:

Answer 1

This other question gave me the answer answer
So the anwser is to add the javax.mail dependency to the plugin as follows :
<build>
....
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.0</version>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>hbm2ddl</goal>
</goals>
</execution>
</executions>
<configuration>
<componentProperties>
<propertyfile>
src/main/resources-${targetprofile}/configuration.properties
</propertyfile>
<export>false</export>
<drop>true</drop>
<outputfilename>
${project.artifactId}-${project.version}-schema.sql
</outputfilename>
</componentProperties>
</configuration>
<dependencies>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.3</version>
</dependency>
</dependencies>
</plugin>

Answer 2

From the error message as well as the debug log, it appears that javax.mail dependency is not part of the dependencies that are present when hbm2ddl is run. Since the contents above are poorly formatted and possibly incomplete, it is difficult to say why. One possibility is javax.mail dependency is not included. Or if yes, included with incorrect (say runtime) scope.
You could try running the goal removing the SMTPAppender from log4j.xml to see if it works. This will help narrow down the problem.
